The Wheatstone bridge is a very useful circuit. When the bridge is fully balanced, the resistance on the right is the same, the resistance on the left (R1=R3, and R2=Rx), and the voltage across the bridge is zero. However, due to a small change in resistance, the bridge becomes unbalanced and a voltage difference appears. Wheatstone bridge applications, such as strain gauges, pressure gauges, sensors and other equipment.
